1. Crescimento e teor de cromo em mamoneira cultivada em solo receptor de resíduos de curtume e carboníferos
RESUMO A produção de resíduos tem aumentado em proporção direta com a industrialização dos países. Sendo assim, a disposição adequada desses resíduos é uma questão largamente discutida entre os órgãos ambientais. Por isso, o objetivo deste trabalho foi estudar o efeito residual de adições sucessivas de resíduos de curtume e da mineração d

3. Biochar from different residues on soil properties and common bean production
ABSTRACT: The production of biochar from organic residues promises to be an interesting strategy for the management of organic waste. To assess the effect of biochar on soil properties and the production and nutrition of common bean (Phaseolus vulgaris L.), three simultaneous experiments were conducted in a greenhouse with different biochar from organic resi

4. Effect of Process Parameters on the Microstructure of Semi-solid ZL101 Aluminum Alloy
Aluminum alloy is the important alloy which has been widely used. To reduce waste, it is necessary to thixoform these alloys in near net shape. Semi-solid slurry is the key in process. In this work, the semi-solid slurry of ZL101 aluminum alloy was prepared by using serpentine channel. Effect of process parameters on the microstructure of semi-solid ZL101 al

5. Analysis of Dimension Stone Waste Addition to the Clayey Mass Used in Roof Tile Production
Addition of dimension stone waste to clayey mass is an alternative to make the dimension stone sector more environmentally sustainable and to reduce the consumption of clayey raw material. Our aim is to study the technical feasibility of dimension stone waste addition to the clayey mass used in roof tile production. Samples of waste and clay were tested for

6. Síntese de nanomateriais de carbono a partir do resíduo de milho (DDGS)
The world's largest ethanol producer (USA) uses corn as feedstock. DDGS (distillers dried grains with solubles) is the main waste generated from this process (around 32 million t/year). DDGS samples were pyrolyzed at 1000 ºC in a furnace with controlled atmosphere. The effluent was channeled to a second furnace, in which catalyst substrates were placed. Chr

7. MODEL PROPOSAL FOR PROCESS MANAGEMENT: CASE STUDY / PROPOSTA DE MODELO PARA GERENCIAMENTO DE PROCESSOS: ESTUDO DE CASO
O enfoque moderno do agronegócio considera todas as empresas que produzem, processam, e distribuem produtos agropecuários. Preocupadas com o desempenho, bem como com desperdícios e perdas com os grãos, as empresas têm-se profissionalizado, implantando tecnologias, criando, planejando e controlando sua gestão. Por outro lado as exigências em mudar o pr
